What is glass safety?

Glass in its standard specification, when broken, will leave shards of glass in the frame or on the surrounding areas. These shards are very dangerous and can cause severe damage to people.

Tempered glass, in contrast, when broken become rounded pebbles which are not dangerous to persons in the surrounding areas.

Generally, all glass below 800 mm from the floor will require safety glass, all door glass will also need tempering and glass panels beside doors will need glass below 1500 from the floor to be tempered.

Please note that tempering the lower sash may only be necessary to comply with these requirements.

The above covers general requirements, however, there may be other areas requiring tempered glass. You should confirm the requirements with professional advisors.

I ordered 15 sliding sash windows for my home refurbishment project and had my builder install the windows for me. I think I spent hours playing around with the different design options on the window builder! I absolutely love my new windows!
